Rules... she spoke of love

Laying in bed and she starts telling how she love the fact that he's has eyes only for her at the moment. She wanted some but the thought of all the hurt he put her through turned her off. Love have limits (boundaries) that arent meant to be crossed or so she say. Why she say there are rules for love??? what the hell are they ??? I mean there are things you just dont do to someone you love but what the basic rules she spoke of??? Loving him for her isnt hard but the heartbreak is horrifying. He doesnt know how much he kills her inside but yet her love for him is never ending or maybe thats just how she feel right now. She's no stranger to me its like I know her inside out but not really. She's a puzzle with pieces that are broken. Though never repaired she would always go on loving him. Rules she spoke of while laying down tangled amongs legs, eyes, hearts, arms, ears. She does the same for me, hear me out when I cry and I do the same for her. Rules... she spoke of love....
